Specs side by side
What owners say
H3
Overall
Mixed sentiment with a clear divide between appreciation for its off-road capability and criticism of its on-road performance, reliability, and value. Long-term owners frequently praise the vehicle's exceptional off-road prowess straight from the factory, citing best-in-class approach and departure angles, available front and rear locking differentials, full skid plates, and capable tires (33-inch). Several owners report high satisfaction with its ability to handle severe terrain without modifications and its utility as a practical, compact off-road SUV.
Best version to buy
Alpha Package or Adventure Package: The V8-powered Alpha version (with the 5.3L engine) is strongly recommended over the standard inline-5 for adequate power, especially for towing (6000 lbs rating vs 4500 lbs) and general drivability. The Adventure Package is noted for including a rear locking differential.
Known issues
- Underpowered 3.7L inline-5 cylinder engine: described as sluggish, struggling with highway merging and towing, "feels like it belongs in a lawn tractor". Frequency: very frequent.
- Transmission reliability concerns: automatic transmissions (particularly the 4-speed) noted as a weak point not expected to last beyond 200,000 miles; specific mention of failures linked to owner misuse (shifting while moving).
- Cooling system problems: tendency to run hot, especially under load or in hot climates; idle temperatures reaching 3/4 gauge indicative of a weak radiator fan; risk of internal radiator failure mixing coolant and transmission fluid ("pink…
FJ Cruiser
Overall
Extremely positive sentiment regarding long-term reliability, durability, and off-road capability. The vehicle is widely described as a "dream car" with a cult-like following, praised for its overbuilt nature, robust 4.0L V6 engine (1GR-FE), and exceptional resale value. Owner discussions consistently highlight its ability to reach very high mileage (200,000-300,000 miles) with proper maintenance.
Best version to buy
Trail Teams Special Edition: Specifically mentioned as a rapidly appreciating collectible with factory off-road enhancements like 16-inch TRD wheels for better sidewall, often commanding 2-3x original MSRP. For general use, models equipped with the automatic transmission are recommended over the manual due to noted issues with the 5-speed manual. 4x4 with a rear locker is the desired configuration for serious off-road use.
Known issues
- Severe blind spots / poor visibility: due to thick C-pillars and small rear window, described as "a blind spot big enough to cover a southern small town scandal." Frequency: very frequent.
- Very poor fuel economy: real-world reports of 14-19 MPG (16.8-12.4 L/100km), with some calculations as low as 4 km/L (approx. 9.4 MPG) in heavy traffic. Frequency: very frequent.
- Extremely high used market prices / "Toyota tax": prices described as "insane," with low-mileage examples commanding near-original MSRP and 200,000-mile examples still demanding high prices. Frequency: very frequent.
